is there a way to hide the “price display suffix” of the products when the VAT is zero?

(I’m currently doing some test on a local test site).

For example, the shop is set in Germany, the products have 19% vat included in their price. The displayed price is let's say “115€ included VAT”.

Customer XY is from the US (under settings / taxes I set the US in the zero taxes table with 0%); he sees the prices without the 19% and that's perfect. The displayed price is “96,64€ included VAT” – even if the VAT is zero and actually isn't there.

Is there a way to hide the label / tag “INCLUDED VAT” when the VAT / tax is zero?

Thanks
